8. Arrhythmia Monitoring
Overview
Arrhythmia monitoring is available for animals only. The selected mode (Full, Lethal or OFF)
determines which events are processed. The monitor compares the received beats to the reference
beats that have been recorded and stored in the reference template. Through this process, the
monitor can identify the occurrence of an arrhythmia event, classify it, and then draw clinically
useful conclusions based on the frequency and type of the signal. The monitor will observe all
beats in question if the baseline moves beyond a defined limit. The monitor uses QRS processing
results for arrhythmia analysis. During multiple lead arrhythmia treatment, the machine measures
the QRS Complex of each lead and compares it to the main learned beats. The monitor classifies
the beats based on information obtained from all available leads.
Arrhythmia Template
ASYSTOLE: Ventricular asystole occurs whenever the displayed heart rate drops to zero.
VTAC/ VFIB: Ventricular fibrillation occurs when the ECG waveform indicates a chaotic ventricular
arrhythmia.
VTAC: Ventricular fibrillation occurs when six or more ventricular beats are detected when the
average heart rate is greater than or equal to 150 beats per minute
ACC VENT: Accelerated ventricular occurs when six or more ventricular beats are detected with an
average heart rate for the ventricular beat between 50 and 100 beats per minute.
BIGEMINY: Occurs when two or more bigeminal cycles (a ventricular beat followed by a non-
ventricular beat) are detected.
BRADY: Bradycardia is the average of the most recent eight R-to-R intervals at a heart rate less
than the set low heart rate limit.
COUPLET: Occurs when two ventricular beats are detected and have non-ventricular beats before
and after the couplet. The coupling interval must be less than 600 milliseconds.
IRREGULAR: Occurs when six consecutive normal R-to-R intervals vary by 100 milliseconds or
more.
PAUSE: Occurs when the interval between two consecutive beats exceeds three seconds.
PVC: Isolated premature ventricular complexes occur when a premature ventricular beat is
